Let me count the ways.
1. Your interface is awful
2. You constantly crash out
3. You continuously kill off my Outlook session preventing it from sending mail, connecting to the mail server and generally working.
4. You steal all the CPU from my laptop.
I'm sure you are supposed to be a better upgrade than the last one, but it certainly doesn't feel like.
Yes, you may be useful but I have had enough. Consider yourself deleted from startup.
